STATEMENT 1: triangle DGH is isosceles
REASON 1: given
STATEMENT 2: DG congruent to DH
REASON 2: definition of isosceles triangles
STATEMENT 3: segment DF is congruent to DI
REASON 3: Given
STATEMENT 4: angle FDG is congruent to angle IDH
REASON 4: Given
STATEMENT 5: construct segments FG and IH
REASON 5: definition of construction
STATEMENT 6: triangle FGD is congruent to triangle IHD
REASON 6: SAS
* The tricky part here was that triangle DGH was isosceles, but you are not told which sides are congruent, so you can pick any pair. That is what I did in STATEMENT 2.
